Yeah i've got it Direct loading and saving of mdl files. Was a lot of work but now it's working.. yiha - Everything is supported, no matter if external skin, materials or lod stages (okay i admit.. lod stages saving might be a bit buggy atm ^^)

That means editing of model skins, materials and vertices is now possible (and will be supported in the next days!).

One example feature (which is allowed by the fact above): Click on an entity, select the skins tab and select skin 1. Click the edit button ==> The Editor automatically opens the skin in Photoshop / Paint / Paint.net (your favorite 2D program). You change it there, press the reload button of the editor... and... tadaa
Will be very interesting for editing of e.g. Normalmaps or Specularmaps.
